Can certain diseases cause paranoia similar to that seen in...

Seizures

Dementia with Lewy bodies

Alcohol withdrawal

Head injury

Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).

Pharmaceutical drug (abuse or side effects)

Mental disorder

Affective disorders

Fever

Migraines

Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:

Alzheimer's disease,

Narcolepsy

Charles Bonnet syndrome

Delirium tremens

⁉️sources from my experiences and internet research ⁉️

Sleep disorders

Stress

Infection

Hallucinogen use

Withdrawal from benzodiazepines

Alcohol

Parkinson's disease

PTSD

Brain Tumors

Bipolar disorder

Grief (yes, sadly)

Can certain diseases cause paranoia similar to that seen in individuals with paranoid schizophrenia, even if they do not have the disorder?
